Roadtrek specific water spill question

[Mike]

I just filled my fresh tank from the land hose using the access tap by the external shower
taps, red valve in the vertical position.
At about the same time the excess water started exiting the right rear door frame filler access plug,
I also noticed water spilling out near the pull valves for dumping the holding tanks behind the drivers
side door. I don't think I've ever seen it do this before and I've filled my fresh tank like this
before via my house's water/garden hose.

Houston, do I have a problem?
I tried searching on here for spill, leaks, overfill, and overflow, but came up with nowt.

Any ideas anyone, normal or otherwise (the spillage, not your ideas )?

TY everyone,
Mike.

I'd say that is normal Mike.

The front tank has a vent that is lower than the front door pillar fill hole. Water will exit the vent when the tank is full. That vent is located very near / above the dump handles.

The rear tank would have an exterior vent tube but it would be quickly overwhelmed by the volume of incoming water and that excess water would exit the rear fill hole.

And you wonder why we see you as"God-like"?
I had a feeling it's probably happened before, but I probably shut off the hose more quickly,
and didn't notice. It does make perfect sense that there'd be another air pressure relief point.
I was inside trying to top up my holding tanks to do a "dump", before we leave for the east coast.

Thanks, it was troubling me just days before leaving.

Mike.

You're welcome Mike.

I wish you wouldn't. I usually learn things the hard way. I've seen lots of sparks etc. and had to patch many mistakes

Have fun on your trip.
